The options can usefully include noatime for better performance (we do not know of any software we run that uses the atime).
/etc/fstab can be prettified using this script (copied from http://unix.stackexchange.com/questions/96037/how-to-align-fstab-entries-easily):
| Code Block |
|---|
#!/bin/bash
# usage: fstabalign [FILE]
# This script will output fstab or other file as column aligned.
# It will not alter blank lines or #hash comments.
if [ -z "$1" ]; then
FILE=$(cat /etc/fstab)
else
FILE=$(cat "$1")
fi
# Separate the file contents into aligned and unaligned parts.
OUT_ALIGNED=$(echo "$FILE" | sed 's/^\s*#.*//' | nl -ba | column -t)
OUT_UNALIGNED=$(echo "$FILE" | sed 's/^\s*[^#].*//' $src | nl -ba)
# Remerge aligned and unaligned parts.
while read; do
line_aligned="$REPLY"
read -u 3; line_unaligned="$REPLY"
line_aligned=$( echo "$line_aligned" | sed 's/\s*[0-9]*\s*//')
line_unaligned=$(echo "$line_unaligned" | sed 's/\s*[0-9]*\s*//')
echo "$line_aligned$line_unaligned"
done < <(echo "$OUT_ALIGNED") 3< <(echo "$OUT_UNALIGNED") |
When run with no arguments, it processes /etc/fstab and writes the aligned version to stdout, from where it can be copied and pasted.
The result, after some manual tidying, is for example:
# /etc/fstab: static file system information.
#
# <file system> <mount point> <type> <options> <dump> <pass>

TODO: enhance the script so less manual tidying is required
